Instructions

Step One:

Disconnect the power to your home. This can be done by flipping the main breaker to the "Off" position.

Step Two:

Remove the cover from the service panel. There may be screws or bolts that need to be removed.

Step Three:

Install the main breaker. The main breaker is the largest breaker in the service panel and it is usually located at the top. To install the main breaker, simply slide it into place and tighten the screws.

Step Four:

Install the branch circuit breakers. The branch circuit breakers are the smaller breakers that are located below the main breaker. To install a branch circuit breaker, simply slide it into place and tighten the screws.

Step Five:

Connect the wires to the breakers. The wires that come into the service panel from the meter will need to be connected to the breakers. To do this, use the wire nuts to connect the wires to the appropriate terminals on the breakers.

Step Six:

Install the grounding electrode conductor. The grounding electrode conductor is a wire that connects the service panel to the grounding electrode (usually a metal rod that is driven into the ground). To install the grounding electrode conductor, simply connect one end of the wire to the grounding electrode and the other end to the grounding terminal in the service panel.

Step Seven:

Install the conduit and fittings. The conduit will be used to protect the wires that run from the service panel to the outlets and switches in your home. To install the conduit, simply cut it to the desired length and then connect it to the service panel and the outlets or switches.

Step Eight:

Turn on the power to your home. Once everything is installed, you can turn on the power to your home by flipping the main breaker to the "On" position.

Tips

* If you are not comfortable working with electricity, you should hire a qualified electrician to wire the service panel for you.

* Make sure that you use the correct size wire for the amperage of the circuit that you are installing.

* Always wear gloves and safety goggles when working with electricity.

* Be sure to follow all local electrical codes when wiring the service panel.
